I am having a problem with the SQL Server 2005 database of our ERP system. We have a scheduled batch that gets stuck because of a lock on a table. The lock remains overnight and halts all other processes (it seems most of them are waiting for this lock to get solved)
I know which table the lock is on and if I kill the lock manually, the batch continues and finishes without a problem
my question is: can I change this behaviour somewhere?
The piece of code that causes this lock is protected, but in a debug log I was able to see that it happens during following actions:
first a select is performed to fetch a certain record in the file that gets locked
next an update is performed with following syntax:
update ... set.... where current of 'pointername'
this update is waiting for a lock to be released before the batch continues.
My guess is that somehow the pointer that is set with the select statements, locks the row and that's why the update cannot be performed.
The strange part is that this lock does NOT occur everytime that this table needs to be updated. And that's why I am stuck and asking help of the real database people :)
If someone can give me a hint on a setup,property, or just a pointer to where I can find more info on the 'why'-part of the lock, I would be very grateful

Hi We are facing an acute situation in our web-application. Technology is ASP.NEt/VB.NET, SQL Server 2000.
Consider a scenario in which User 1 is clicking on a button which calls a SQL stored procedure. This procedure selects Group A of records of Database Page1.
At the same time if User 2 also clicks the same button which calls same SQL stored procedure. This procedure selects Group B of records of Database Page1.
So, its the same Page1 but different sets of records. At this moment, both the calls have shared locked on the Page1 inside the procedure.
Now, in call 1, inside the procedure after selecting Group A of records, the next statement is and update to those records. As soon as update statement executes, SQL Server throws a deadlock exception as follows :
Transaction (Process ID 78) was deadlocked on lock resources with another process and has been chosen as the deadlock victim. Rerun the transaction
We are able to understand why its happening. Its because, Group A and Group B of records are on the same Page1. But both the users have shared lock on the Page1. So, no one gets the exclusive lock in records for update, even though, the records are different.
How can I resolve this issue? How can I get lock on wanted rows instead of entire page?
We have 350 tables in our database, I want to drop/delete those table(s) that are inactive. Is there a way to check which tables are not active, so I could drop/delete that table(s).
Here are two tables. How do i create an SP for INACTIVE delete and how do i use the UNIQUE constraint to avoid duplication of the NAME columns(logingroup_name and login_name) in these tables?
--Creating Table ref_LoginGroup:- create table ref_LoginGroup ( logingroupid tinyint identity(1,1) constraint pklogingroupid primary key clustered, logingroup_name varchar(25) constraint chkname check(logingroup_name NOT LIKE '% %'), changed_login_id int, is_active bit, lastupdr smalldatetime, ) --Creating Unique nonclustered Index for ref_LoginGroup:- create unique nonclustered index idxlgn on ref_LoginGroup(logingroup_name)
--Creating Table ref_Login:- create table ref_Login ( login_id int identity(1,1) constraint pkloginid primary key clustered, login_name varchar(50) constraint chklogname check(login_name NOT LIKE '% %'), firstname varchar(30), lastname varchar(30), logingroupid tinyint constraint fklogingroupid foreign key references ref_LoginGroup(logingroupid), changed_login_id int, is_active bit, lastupdr smalldatetime ) --Creating Unique nonclustered Index for ref_Login:- create unique nonclustered index idxl on ref_Login(login_name)
My db is working in simple recovery mode, when I run "dbcc sqlperf(logspace)", I find the log file is very large and the log usage percentage is 98%. In most case, when I run "backup log db_name with no_log", the log usage percentage will be reduced. but in fact it is no change. I make sure there are no active logs in it. Who can tell me the reason ? thx.
I have a snapshot & a transcation publication on Server A, and a pull subscription for each on Server B.
The distribution agent on ServerA has the error:
"The subscription(s) have been marked inactive and must be reinitialized. NoSync subscriptions will need to be dropped and recreated."
Any idea what caused this ..... Everything was fine for a week or so.
Does anyone know of any good books or publications on Replication ? I've got some DBA books that cover the basics, but I'd like something that helps explain the oddball situations.
I am working at a site that has no dedicated DBA, and our Sql Server 2000 environment has recently been playing up. There are several databases on the Production server that should be inactive (for applications no longer used).
What is the best way for me to see if there has been any recent activity on these databases (short of taking them offline and waiting for screams). Please keep in mind that I am a Sql Server novice.
Hi, I have set of 2 DTS packages, one of which calls the other by forming a command-line (dtexec) using a Execute Process task.
From the parent package-> Execute Process Task-> dtsexec /F etc... /<pkg variable> = "servername"
Each of the parent and the called package have a variable: "User::DWServerSQLInstance" which is mapped to the SQL server connection manager server name property using an expression. The outer package has the above variable and so does the inner called package (which gets assigned through the command line from the outerpackage call to inner)
I "sometimes" get the following error:
OnError,I4,TESTDOMAdministrator,ACDWAggregation,{A1F8E43F-15F1-4685-8C18-6866AB31E62B},{77B2F3C7-6756-46EB-8C01-D880598FB4B3},5/22/2006 5:10:28 PM,5/22/2006 5:10:28 PM,-1073659822,0x,The variable "User::DWServerSQLInstance" is already on the read list. A variable may only be added once to either the read lock list or the write lock list.
Help would be appreciated!
I have seen other posts on this but, not able to relate the solution to my scenario.
Does anyone know if there is a 3rd party tool available to disconnect user logins after being inactive for a period of time? Is this something that can be custom written?
hi,i've just restored my db and when i try to login with a user (even ifthe user is "sa"), an error occours.The error is "User sa is currently inactive"How can i solve this problem?Thanks,Massimo
I' d like to list all inactive clients.Inactive client is a client who hasn't had invoice for 2 months.I use INNER JOIN to join invoice view (vwDok4FSFZGrid) and clientsaddresses table (adr_Nazwa). I skip empty values (adr_Ewid.adr_Nazwa !=''). I select only invoices with date after the interesting date.So now I can list all active clients but i can't negate this resultset to get all inactive clients:SELECT dok_PlatnikId, adr_Nazwa,adr_NazwaPelna,adr_Adres,adr_Miejscowosc,adr_NIP, dok_DataWystFROM vwDok4FSFZGridINNER JOIN adr__EwidON vwDok4FSFZGrid.dok_PlatnikId=adr__Ewid.adr_IdObiek tuWHEREadr__Ewid.adr_Nazwa !=''AND(dok_DataWyst >= convert(datetime,'10/03/2007'))GROUP BY dok_PlatnikId, adr_Nazwa,adr_NazwaPelna,adr_Adres,adr_Miejscowosc,adr_NIP, dok_DataWystIs there any way to negate this set?1. Sorry for my English2. I would appreciate any help:)
Package works fine when run from BIDS, DTExec, dtexecui. When I schedule it, It get these random errors. (See below)
The main culprit is a variable called "RecordsetFileDIR" which is set using an expression. (@[User::_ROOT] + "RecordSets\")
A number of other variables use this as part of their expression and as they all fail, pretty much everything dies.
I have installed SP1 (Not Beta) on server. Package uses config files to set the value of _ROOT.
The error does not always seem to be with this particular variable though. Always a variable that uses an expression but errors are random. Also, It will run 3 out of 10 times without a problem. I am the only person on the server at the time.
Any ideas?
Cheers,
Crispin

A Contractor has a list of Contracting Companies that he has worked for in his history.
For each row in the "Contracting Company" table, there is an Active Date and an Inactive Date. Each Contracting Company cannot have overlapping dates.
The last row in the table for that Contractor may have a null Inactive Date. That just means that he doesn't know when his contract will end.
In Report Builder, I can access the "Last Active Date", because there is a pre-built formula for "Last Active Date". However, whenever I access the prebuilt formula "Last Inactive Date" - I get the inactive date for the second-last row, because the last row has a null value for the Inactive Date! I want to get the Inactive Date for the last row - not the second last row!
Hi AllgI have problem in using the SQLDataSource. When in VS 2005 I drag and drop the SQLDataSource onto my page and then add a GridView control.I bind the GridView control to the SQLDataSource control. But the problem is it does not generate the INSERT, UPDATE, and DELETE statements. The dialog box is inactive. The screenshots may help. please help me in this regard. I also tried it for Accesscontrol but the same problem.

I have a Development Machine running Windows XP Professional SP2, with SQL Server 2005 including Reporting Services. I am developing an ASP.NET application using VS 2005, and am including Server Side Reports from SQL Server. Everything is working well, except when viewing the Reports.
The Reports when viewed from Reporting Services€™ Report Manager or from within the ASP.NET application only display the first page of the report, displaying the total number of pages as 0. As well, most of the functions on the report toolbar appear to be disabled. This occurs for any report viewed, even sample reports such as the Adventure Works Samples.
The problem only occurs when viewed from within Internet Explorer on the Development Machine. To overcome the problem, I have upgraded SQLServer to SP2, and removed and reinstalled Internet Explorer, but it made no difference. It appears to be related to the rsClientPrint ActiveX addon which should have been installed when the print icon was first selected. It appears not to have installed properly, but up to that point everything worked OK. Selecting the Print icon (or any other icon) since nothing happens. I€™m guessing here, but I suspect that the rsClientPrint addon needs to be reinstalled, but I don€™t know how to go about it. It is not listed within IE addon (where it is on other machines connecting to the Development Machine), nor is it listed within the €œC:WindowsDownloaded Program Files€?. But it is not being downloaded when the Print Icon is selected. I have checked all the Security settings for the environment to ensure that ActiveX programs are downloaded, and everything appears to be in order.
Would anyone be familiar with this problem or have any suggestions on how to go about resolving it? Any help would be appreciated as it is causing significant problems. Strange though, the reports appear fine when viewed from within the Server Manager.
I want to lock a table so others cannot lock it but able to read it inside transactions.
The coding I need is something like this: set implicit_transactions on begin transaction select * from table1 with (tablock, holdlock) update table2 set field1 = 'test' commit transaction commit transaction
I have tried the coding above, it won't prevent others from locking table1.
So, I changed the tablock to tablockx to prevent others from locking table1. But this will also prevent others from reading table1. So, how can I lock table1 so others cannot lock it but still able to read it?
The sqlserv.exe takes too much CPU utilization on my SQL 2000 on W2K production machine. I am tring to use System Monitor to monitor the Thread/%process time with all Sqlservr instances, and then match the sqlservr instance number to the KPID in sysprocesses table to find out which user is causing the problem. but I can only see the instance number from Sqlservr0 to sqlservr99. From the table sysprocesses table, the KPID is all 3 or 4 digits number. Any one has any idea about this?

Just wondering if there is any way to kill a thread within an sqlerver process. The thread we are trying to kill is a rollback statement that has been running for a very long time.
The thing that I dont understand is, where the thread get the information from? My windows application currently set to "zh-CHS" culture but my pc that running the application is "en-US".
It seems like the thread get the information from my pc. What i want is, getLanguage get the information from the application.

I have identified that one of the instance is taking much more CPU than the other by using the counter process\% processor time in perfmon. So we have decided to monitor only that instance using ID Thread counter to see which process is causing this high usage within this instance.
Now problem... Thread ID is re-used by Windows. We cannot identify which counter is the one causing problem at that point of time just using the ID from a report given to me NEXT DAY because I can never dream of monitoring the server in the real time to see what is the process Thread ID NOW.
Now question.. Is there is any counter that says which process caused the spike in %CPU used at one point of time from the thread id comparing against another counter in perfmon?
I have never worked with this in detail before. If any one can give me the counters and the method to identify which process is related to which thread at that point of time from a report received NEXT DAY MORNING, thanks a lot.
Hello, I have built a system, that uses a .dll file for all SQL operations. So a program looks something like this: using myDLL; .... SQLDBCON mSQL = new SQLDBCON(); and here comes the rest of the program. My question is, the dll file has all stored procedures and when you declare mSQL as shown above, then it opens a thread to the database for that user. Is that thread properly closed when the site has finished loading? in my .aspx page i dont have a function like mSQL.CloseDB(); and if i try to add something like this to the dll file ~SQLDBCON { m_local_con.Close();m_local_con.dispose(); } i get a error message says something that this is not allowed. Just want to know if my thread in the dll file is properly closed?
Hi all, I am having problem with SQL connection at Godaddy where my pool connection gets MAX OUT. When it happens, I cannot access the database.This is the thread about the problem: http://forums.asp.net/thread/1665023.aspx I just created this with "THREAD". I hope someone who has experiences with thread can give me some advice about my design. This is my first time.
static object Locked = new object(); public object ExecuteCommand(string queryStr, string type){ //*************************************************************************************// // ExecuteCommand: Returns an object // //*************************************************************************************// Thread t = null; lock(Locked) { SQLString = queryStr; switch(type) { case "ExecuteNonQuery": t = new Thread(ExecuteNonQuery); break; case "ExecuteScalar": t = new Thread(ExecuteScalar); break; case "GetDataReader": t = new Thread(GetDataReader); break; } t.Start(); t.Join(); } return null;} First of, does this work at all? It runs, but is it a good design in term of Thread? Since I use LOCK, do I still need the t.Join() function? The switch with the three cases, is that OKAY? Basically, I'm clueless. If you read my other post, you will get an idea what I'm trying to do. Any feedback would be very very appreciated. Thank you.
